In the first example rung above, when transitional contact I1 goes on, 5 registers (R1 –
R5) are copied to locations R10 – R14.
In the second rung, each program scan 128 bits (8 x 16) are copied from O9 – O137 to
locations O17 – O124. Since the locations being copied from overlap the locations being
copied into, this function actually has the effect of shifting 128 bits eight bits to the “left”
(that is, to higher locations) in memory.
